A straight line passing through A(3,2) and B(5,y) has gradient -2. find the value of y

astraxan [27]

Step-by-step explanation:

$gradient \: = \: \frac{y2 - y1}{x2 - x1}$

y2 = y , x2 = 5

y1 = 2 , x1 = 3

$- 2 \: = \: \frac{y - 2}{5 - 3}$

-4 = y-2 ==> y = -2

Answer:

Step-by-step explanation:

Given:

$C_{(x)}=-0.00001x^{2}-0.02x+49$

for x≤1400; N = 5

So, Δx = $\frac{1400-0}{5} =280\\\\\int\limits^{1400}_0 {C(x)} \, dx$ =∑C(a + nΔx).Δx

=C(0)Δx + C(280)Δx + C(560)Δx + C(840)Δx + C(1120)Δx

= Δx[C(0) + C(280) + C(560) + C(840) + C(1120)]

= 280[49 + 42.616 + 34.664 + 25.144 + 14.056]

=280[165.48]
